11/15/2007 Algebra 1-Writing Equations of Lines(Given Slope & Y-Intercept and Slope & Point)

Today we begin Chapter 5, shifting our focus from graphing equations to writing equations given certain information. Our objectives our:

1) Write the equation of a line given the slope and y-intercept
2) Write the equation of a line given the graph
3) Write the equation of a line given the slope and a point
4) Write the equation of a line given the slope and x-intercept
5) Write the equation of a line parallel to a given line thru a given point

Examples of these problems can be found here (click on Example 2) and here (click on Example 2). I did some example problems on the board in the notes, then students practiced on a worksheet and some problems from the book,

11/15/2007 Pre Algebra-Greatest Common Factor

Students will be reviewing greatest common factor today. They will take some notes over some example problems on the board and then practice on a worksheet. They will be finding the greatest common factor of 2 numbers, deciding if 2 numbers are relatively prime and finding the greatest common factor of monomials (example: 3x and 27x).
